OF ROCKAWAY BEACH, NEW YORK.

INTERNAL-COMBUSTION ENGINES.

Patented July 6, 1915.

Application filed November 24, 1914. Serial No. 873,805.

To all whom it may concern:

Be it known that I, FREDERICK WM. GEORGE, a citizen of the United States of America, residing at Rockaway Beach, in the county of Queens and State of New York, have invented new and useful Improvements in Cooling Apparatus for Internal-CombustionEngines, of which the following is a specification.

This invention relates to improvements in apparatus for cooling internal combustion engines and has particular application to apparatus of the type in which air or gas is passed through the liquid of the circulatory cooling system.

In carrying out the present invention, it is my purpose to provide apparatus for cooling internal combustion engines wherein the circulating water flowing from the engine back to the radiator will be divided up into individual streams and sub ected to a blast of air so that the cooling medium bearing the heat units will be rapidly and effectively cooled and then passed through the radiator for further cooling so that when this portion of the cooling medium again flows through the water jackets of the engine cylinders and other parts, such cooling fluid will be in a condition to receive the heat units from the cylinders and carry the same away so that they may be dissipated by the air blast and radiated from the cooling cells of the radiator.

It is also my purpose to provide apparatus of the class described which may be installed and maintained at a minimum expense and wherein the cooling liquid of the engine .will be effectively and rapidlv relieved of the heat units therein.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling Within the scope of the claims.

In the accompanying drawings, Figure l is a view inside elevation of an internal combustion engine provided with cooling apparatus constructed in accordance with the present invention. Fig. 2 is a fragmentary vertical sectional view through the radiator showing the means for dividing the water into individual streams and blowing air thereon. Fig. 3 is an enlarged fragmentary cross sectional view through the radiator taken at right angles to Fig. Fig. 4: is a horizontal sectional view through the radiator showing the cooling tube in top plan. Fig. 5 is a perspective view of the cooling tube removed from the radiator. Fig. 6 is a vertical central sectional view through the radiator showing a modified form of the invention. Fig. 7 is a similar view taken at right angles to Fig. 6.

Referring now to the drawings in detail, 1 designates a radiator of any approved construction having the upper end portion thereof formed to provide a compartment 2 disposed above the cooling cells and pr videcl with a top edge wall 3 formed centrally with an upstanding vent spout l. Leading from the lower end edge of the radiator 1 and in open communication with the cooling cells thereof is a pipe 5 extending to and connected with the water jackets of the engine cylinders, and connected with the upper ends of the water j ackets is a pipe 6 leading into the upper end of the radiator 1 through one of the walls of the chamber 2. By means of this construction, it will be seen that the cooling water may circulaa: through the cooling cells of the radiator and the water jackets of the engine cylinders, such water flowing from the bottom of the radiator through the pipe 5 into the cooling jackets of the engine cylinders, and then through the pipe 6 backto the upper end of the radiator.

In accordance with my present invention, a tube 7 is disposed within the compartment 2 and extends longitudinally of the radiator and has the opposite ends thereof secured by means of appropriate brackets 8 to the respective end walls of the radiator so that the tube may be supported within the chamher 2 in parallelism with the top edge wall thereof. The top wall of the tube 7 is formed with one or more longitudinally extending rows of orifices 9 and secured to the top portion of the. tube and extending longitudinally thereof and inclosing the orifices 9 is an inverted trough 1O semi-circular in cross section and having the top portion thereof provided, approximately centrally, with an upstanding nipple 11 connected with the adjacent end of the pipe 6. One end of the tube 1 opens into the cells of the radiatorand the oppositeend portion thereof is formed with a right angular elbow 12 within which is disposed a blast fan 13 driven from the engine through the medium of suitable driving means 14.

In practice, as the water circulates through streams of water flow into the tube an air blast from the fan 15 strikes the same, thereby effectively cooling water preparatory to the latter passing through the cells of the radiator, and as the water passes through the cells of the radiator the action of the air blast is augmented and the water further cooled. This air from the blast fan 13 is preferably blown down through the cells 1 and tapped into the lower end of the radiator is the lower end of a vertical exhaust pipe 15, such pipe having the upper end thereof terminating above the water line of the radiator so that the air may be exhausted from the system.

In the modified form of the invention illustrated in Figs. 6 and 7, the lower half of the tube 1 is removed or cut away and suspended from the under surface of the remaining portion of the tube contiguous to the respective rows of'orifices 9 are cloths 16 depending into the radiator and designed to receive the water passing through the orifices 9 and hold such water in contact with the air for a relatively long time.

In practice, I wish it to be understood that the lower portion of the radiator, that is, the portion below the chamber 2, may be in the form of a tank in lieu of cooling cells of coils.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that I have provided a cooling system for internal combustion engines whereby the cooling liquid after passing through the engine cylinders is divided into a plurality of independent streams and subjected to an air blast, thereby enabling the fluid to be rapidly and effectively cooled.

While I have herein shown and described certain preferred forms of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification 'and'variation may be made within the scope of the claims without departing from the spirit of the invention.

The front wall of the chamber 2 is preferably formed with a rectangular opening 2 and hinged to the upper wall of the opening 2 is a cover plate 3 normally overlying the opening 2 and closing the latter and capable 1. A radiator for the cooling systems of internal combustion engines having a water inlet connection at the upper end thereof and a Water outlet connection at the bottom end thereof, a tube disposedwithin the upper end portion of said radiator and having the wall thereof formed with a series of apertures extending longitudinally thereof, an inverted trough secured to said tube and inclosing said apertures and extending longitudinally of the tube and connected with the water inlet connection of the radiator whereby the water will flow through the trough and through the apertures into the tube in the form of individual jets, and a blast fan at one end of said tube adapted to blow air into the latter against the streams of water therein to facilitate the cooling of such Water.

2. A radiator for the cooling systems of internal combustion engines having a water inlet connection at the upper end thereof and a water outlet connection at the bottom end thereof, a tube disposed within the upper end portion of said radiator and having the wall thereof formed with aseries of apertures extending longitudinally thereof, an inverted trough secured to said tube and inclosing said apertures and extending. longitudinally of the tube and connected with the water inlet connection of the radiator whereby the water will flow through the trough 'and through the apertures into the tube in the form of individual jets, and a blast fan atone end 'of'said tube adapted to blow air into the latter against the streams of water therein to facilitate the cooling of such water, the portion of said tube opposite from the apertures being cutaway and cloths secured to the remaining portion of said tube adjacent to the respective rows of apertures therein and depending therefrom to receive the water and hold the latter in contact with the air for a relatively long time.

In testimony whereof I aflix my signature in presence of two witnesses.
